Abstract:  Thirty-nine plankton samples were collected at the Drift Station
     "Arlis II" at the north of Greenland in the Arctic Ocean during the period
     from June to December, 1964.  From the samples thirty-two species of
     copepods were identified, of which Calanus glacialis, C. hyperboreus,
     Microcalanus pygmaeus, Spinocalanus abyssalis, Metridia longa and Oithona
     similis were major components.
	   The maximum plankton biomass throughout the period was observed in
     July when C. hyperboreus was predominant.  The plankton population during
     day season (light season from June to August) was characterized by
     abundance of C. hyperboreus, M. pygmaeus and O. similis, while the
     population during night season (dark season from September to December)
     was characterized by abundance of M. pygmaeus and O. similis.
	   Developmental stages of C. hyperboreus were collected in bulk in
     summer, suggesting that this species was breeding under the permanent ice-
     floe.

Side Notes:  This research was supported by the Project 'ONR-335' of the Office
     of U.S. Naval Research.  Filtration ratio is included in the metadata, but
     was not coded for the database.  Execerpt from methods section defining
     the filtration ratio is as follows:  The volume of water filtered by the
     net was calculated from the records of a flow-meter (RGS No. 432) attached
     to the net.  Filtration ratio of the net was estimated as 0.95 on the
     average.
